Palestinian witnesses say a large explosion damaged the Gaza offices of an Arabic satellite television network. No one was injured in the blast.

It was not immediately clear what caused the explosion or who was responsible for it. The blast damaged the door and interior walls of the offices of Dubai-based Al-Arabiya television.

Authorities say no one was in the offices at the time of the explosion.

Officials from the Hamas-led Palestinian government condemned the attack. Hamas has recently criticized Al-Arabiya for broadcasting comments by Prime Minister Ismail Haniyeh that the group says were taken out of context.
